Searches for R -parity-violating supersymmetry in pp collisions at s =8 TeV in final states with 0-4 leptons
(2016-12-29)
Results are presented from searches for R-parity-violating supersymmetry in events produced in pp collisions at s=8 TeV at the LHC. Final states with 0, 1, 2, or multiple leptons are considered independently. The analysis ...
Search for supersymmetry in events with one lepton and multiple jets in proton-proton collisions at s =13 TeV
(2017-01-27)
A search for supersymmetry is performed in events with a single electron or muon in proton-proton collisions at a center-of-mass energy of 13 TeV. The data were recorded by the CMS experiment at the LHC and correspond to ...
Measurements of the tt¯ production cross section in lepton+jets final states in pp collisions at 8 TeV and ratio of 8 to 7 TeV cross sections
(2017-01-07)
A measurement of the top quark pair production (tt¯) cross section in proton–proton collisions at the centre-of-mass energy of 8TeV is presented using data collected with the CMS detector at the LHC, corresponding to an ...
Measurement of the top quark mass using single top quark events in proton-proton collisions at √s=8 TeV
(2017-05-29)
A measurement of the top quark mass is reported in events containing a single top quark produced via the electroweak t channel. The analysis is performed using data from proton-proton collisions collected with the CMS ...
Search for dark matter and unparticles produced in association with a Z boson in proton-proton collisions at s =8 TeV
(2016-03-22)
A search for evidence of particle dark matter (DM) and unparticle production at the LHC has been performed using events containing two charged leptons, consistent with the decay of a Z boson, and large missing transverse ...
Measurement of the t t ¯ production cross section using events in the e μ final state in pp collisions at √s=13 TeV
(2017-03-20)
The cross section of top quark–antiquark pair production in proton–proton collisions at s=13TeV is measured by the CMS experiment at the LHC, using data corresponding to an integrated luminosity of 2.2fb-1. The measurement ...
Measurement of the transverse momentum spectrum of the Higgs boson produced in pp collisions at √s=8 TeV using H → WW decays
(2017-03-07)
The cross section for Higgs boson production in pp collisions is studied using the H → W+W− decay mode, followed by leptonic decays of the W bosons to an oppositely charged electron-muon pair in the final state. The ...
Decomposing transverse momentum balance contributions for quenched jets in PbPb collisions at √sNN=2.76 TeV
(2016-11-09)
Interactions between jets and the quark-gluon plasma produced in heavy ion collisions are studied via the angular distributions of summed charged-particle transverse momenta (pT) with respect to both the leading and ...
Charged-particle nuclear modification factors in PbPb and pPb collisions at √sNN=5.02 TeV
(2017-04-07)
The spectra of charged particles produced within the pseudorapidity window |η| < 1 at sNN=5.02 TeV are measured using 404 μb−1 of PbPb and 27.4 pb−1 of pp data collected by the CMS detector at the LHC in 2015. The spectra ...
Measurement of prompt and nonprompt J / ψ production in p p and p Pb collisions at √sNN=5.02TeV
(2017-04-27)
This paper reports the measurement of J / ψ meson production in proton–proton (p p) and proton–lead (p Pb) collisions at a center-of-mass energy per nucleon pair of 5.02TeV by the CMS experiment at the LHC. The data samples ...
